I have been using the Cellerciser consistently (3 -4 times per week) for only 3 weeks now but I have to tell you …. I am over the moon about how I am feeling and what I am seeing. My whole body is changing. I’m feeling muscles in my arms that haven’t been there in years. I also had a lot of saggy skin that was from earlier weight loss on my face and arms and that has greatly improved already!! And the way my brain feels right now at 56 is AMAZING. I feel so much better mentally and feel more alert and alive. You may remember my phone call a few weeks back about plantar fasciitis? I called because I had had so many issues with that during the last 20 years … and it started to bother me again when I first started using the Cellerciser which made me panic. I called and talked with you Dave, and you read me a few reviews on how bouncing has helped people with this problem, but I was still a bit skeptical to but it nicely. However, I loved the way bouncing made me feel so I kept Cellercising. Sometimes with my shoes on but mostly with bare feet at this point. Guess what? Plantar fasciitis is completely GONE! No signs of it and my feet feel better than they have since I was in my 20s. My sister Marie started this Cellercising revolution in my family a few months back and out of a family of seven …. Five of us have a Cellerciser and love it. We are working on the last two brothers and telling them it is so worth the investment. My brother Daniel came and bought one at your factory on his 70th birthday and is one of your biggest proponents. He came there to get a picture with Dave, but you weren’t in the office that day. Couldn’t be happier and will definitely continue to tell everyone about this amazing product. Every home should have one … it is rolling back the clock for me.
